MANUFACTURE OF SECTIONS OF FIBRE-PLASTIC COMPOUND MATERIALS

摘要

The method for the manufacture of sections of fibre-plastic compound materials is carried out by means of at least one draw nozzle (10). In this nozzle, fibres (41) which are impregnated with flowable plastic (42) are formed under pressure to a product (41) with a predetermined cross-section and consolidated with the withdrawal of heat. The cross-sectional surface of the draw nozzle is periodically increased and decreased in time in its entire shape imparting region, with a value for the frequency of the oscillating cross-sectional surface being chosen less than 1 kHz, preferably less than 100 Hz.
